Murphy Ring Splints are designed to give freedom of motion to people with swan neck deformity. They does so by restricting abnormal hyperextension of the digit and allowing free flexion at the proximal interphylangeal joint (P.I.P. joint). Murphy Ring Splints can be used for rheumatic disease or other conditions where swan necking of the P.I.P. joint occurs.

More On Murphy Ring Splints

Why splint Swan Neck Deformities?

  • To allow free functional grasp without manual movement of the affected joints from locked hyperextension to flexion.
  • To limit additional damage to the joint which occurs when the finger repeatedly moves from flexion to hyperextension.
  • To decrease swelling of the P.I.P joint. Decrease in swelling may occur in many cases after several months of splint wear.

How does the Murphy Ring Splint work?

After being fit correctly on the finger
  • The single wrapped end prevents the finger distal to the P.I.P. joint from moving into hyperextension, thus preventing the digit from becoming locked in the swan neck position.
  • The double wrapped end serves as an "anchor" to secure the splint proximal to the P.I.P joint.
  • The junction of the ends of the splint, under the P.I.P joint, does not block movement but allows free flexion of the digit.
